yDo not open or damage batteries. Released electrolyte is harmful to the skin and eyes. It may
be toxic.
yA battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries.
a) Remove watches, ring, or other metal objects.
b) Use tools with insulated handles.
c) Wear rubber bloves, boots and glasses
d) Do not lay tools or metal parts on top of battery.
yDo not leave the ESS in the Fault standby state for a long time because of the battery
discharge may occur during the long standby state.
yIf the battery fault occurs immediately after starting PCS it means Battery failure. Check the
battery SOC also voltage and fault information, and turn off the power of the ESS until service
action is taken.

yIf the battery SOC is low the battery may charge from the grid for self-protection. (Emergency
Charging) This function is to prevent shutdown of the ESS, deep discharge and failure of the
Battery Extension Kit. An Emergency Charge is not an ESS fault.
NOTE
Indicates a risk of possible damage to the product.
yBefore making connections, please make sure the PV array open circuit voltage is within 800
V. Otherwise the product could be damaged.
yNever use any solvents, abrasives or corrosive materials to clean this product.
yDo not store on or place against any objects to the product. It may cause serious defects or
malfunction.
yBefore making a connection, make sure the PV switch on this product is switched off.
yThis unit is designed to feed power to the public grid only. Do not connect this unit to an

Glossary
Terms Explanation
Azimuth In the Northern hemisphere, the azimuth angle indicates by how much
degrees the module surface deviates from a full south aspect. In the
southern hemisphere, it indicates the deviation from a full north aspect.
The azimuth angle is counted with positive values within the range from
south (0°) to west (90°) and it counted with negative values within the
range from south (0°) to east (-90°).
Tilt angle The tilt angle indicates by how much degrees the tilt of the module surface
deviates from the horizontal.
PV module The PV module refers to a panel designed to absorb the sun’s rays as a
source of energy for generating electricity.
PV array Technical device for the conversion of solar energy into electrical energy. All
serial and parallel installed and connected to PV modules of a PV system
are referred to as a PV array.
